Compact, Lightweight and Low Cost Thermal Management System for Active Denial Technology (ADT) and High Power Radio Frequency Vehicle Stopper (RF) Systems Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-110 Topic Title: Compact, Lightweight and Low Cost Thermal Management System for Active Denial Technology (ADT) and High Power Radio Frequency Vehicle Stopper (RF) Systems Proposal No.: N102-110-0760 Firm: Altex Technologies Corporation 244 Sobrante Way Sunnyvale, California 94086 Contact: John Kelly Phone: (408) 328-8302 Web Site: http://www.altextech.com Abstract: Active Denial Technology (ADT) and RF Vehicle Stopper devices need compact, light weight and low cost thermal management systems to meet mission goals. Heat exchangers strongly contribute to system volume, weight and cost. Innovative heat exchanger concepts have been identified that can reduce volume, weight and cost by over 60%, 80% and 50%, respectively, thereby helping to meet the system goal of a factor of two reduction in volume, weight and cost. Under the proposed project, the innovative heat exchanger technologies will be integrated into a next generation thermal management system for ADT and RF Vehicle Stopper devices and the design will be analyzed to show that steady and transient system performance meets Navy requirements for performance, volume, weight and costs. In addition, the heat exchangers will be tested with phase change materials to evaluate performance augmentation. While meeting ADT and RF Vehicle Stopper device requirements, the thermal management system approach will also be viable for other directed energy weapons, as well as civilian applications. Benefits: By using the proposed innovative heat exchangers in the ADT and RF Vehicle Stopper cooling system, heat management goals will be achieved at a factor of two lower volume, weight and cost. These reductions in weight and volume will facilitate mission goals. Furthermore, when the heat exchangers are implemented in both military and civilian HVAC applications, the innovation will save over $7.7 billion per year in energy costs, save 0.26 quad of energy and reduce CO2 emissions by 70 million tons/year.
